Error recognizing modules behind a macro

Environment

• IntelliJ Rust plugin version: 0.2.111.2147-193
• Rust toolchain version: 1.40 nightly
• IDE name and version: CLion 2019.3
• Operating system: Windows 10

Problem description

One of the most popular crates, tokio, has modules which cannot be parsed by the plugin. Examples include the tokio::sync::mpsc module, which is imported inside a macro:

cfg_sync! {
    mod barrier;
    pub use barrier::{Barrier, BarrierWaitResult};

    pub mod mpsc;

    mod mutex;
    pub use mutex::{Mutex, MutexGuard};

    pub mod oneshot;

    pub(crate) mod semaphore;

    mod task;
    pub(crate) use task::AtomicWaker;

    pub mod watch;
}

mpsc is not recognized by the plugins at all.

Steps to reproduce

Use tokio, try to include tokio::sync::mpsc::Whatever, see error.

It’s fixed in #4914 and will be landed in the next release (I hope). I close this issue as a duplicate of #4627 because they have the same reason

Yeah it can’t detect the tokio TcpListener too, just keeps importing the std::net one.
